Deployment Adjustments for Recovery & Hot-Swapping

  • Recovery only for all Cornell Rockhopper sites and UMCES sites T-2C, T-3C

  • Addition of VR2ARs in place of VR2Ws and Sonardyne acoustic releases for redeployed UMCES sites

    • UMCES sites to be redeployed: T-1C, V5, A-5C, V4
  • Removal of co-deployed C-POD and LS-1X at sites T-1C and A-5C; VR2Ws replaced by VR2ARs

  • Addition of an F-POD at site V5 and an LS-1X at site V4

    • Mooring configuration:

      • LS-1X and F-POD placement above VR2ARs (necessary for acoustic release mechanism)

  • Estimated max. time needed at stations:

    • Tonal Playbacks - 10 mins

      • Goal to conduct playbacks for all Rockhoppers currently deployed in array (A1M-A7M) on first day of cruise
    • Rockhoppers - 10 mins

      • Retrieval only
    • UMCES multi-device moorings - 15 to 30 mins

      • T-2C, T-3C – 15 mins

        • F-POD + VR2W + Sonardyne AR recover
      • D1, D2 – 15 mins

        • F-POD + Sonardyne AR recover
      • V4, V5 – 15 mins

        • VR2AR recover

        • VR2AR + LS-1X or F-POD redeploy

      • T-1C, A-5C – 30 mins

        • F-POD + C-POD + LS-1X + VR2W + Sonardyne AR recover

        • F-POD + VR2AR redeploy

Day 1 - Tuesday, 16 April 2024

Goals: Perform 5 tonal playbacks. Recover 5 Rockhopper, 2 solo F-POD, 1 VR2AR, and 2 F-POD/VR2W moorings. Redeploy 3 F-POD/VR2AR moorings.
